Abstract

The invention discloses a method for preparing thiolated nano ferroferric oxide magnetic polymer composite material. The method comprises the following steps of: dissolving Fe2<+> and Fe3<+> in water, wherein a dropwise adding system is alkaline, heating, stirring to react, washing until the pH value is 7, and drying the reaction product; adding an ethane solution into the reaction product, heating, and adding an oleic acid with stirring; adding a dispersing agent, adding a monomer for polymerization, an epoxy functional monomer and a cross-linking agent, and performing ultrasonic dispersion;adding an initiator, heating, stirring to react, washing until the pH value is 7, performing magnetic separation and drying the reaction product; performing ultrasonic dispersion, adding an epoxy vulcanizing reagent, heating, stirring to react, washing until the pH value is 7, performing magnetic separation and drying the reaction product; and performing ultrasonic dispersion, dropwise adding NaHS solution, stirring to react, washing until the pH value is 7, performing magnetic separation and drying the reaction product to obtain the target product. The invention has the advantages of simple preparation method, low cost, uniform particle size distribution, stable performance and capability of absorbing and removing superstandard heavy metal Hg from water, of the obtained target product, innocent treatment, water resource protection and the like.

Description

technical field [0001] The invention relates to a preparation method and application technology of a mercaptolated nano ferroferric oxide magnetic polymer composite material with a core-shell structure, in particular to a preparation method of a mercaptolated nano ferroferric oxide magnetic polymer composite material. The nanometer magnetic polymer material prepared by the invention can absorb and remove excess heavy metal mercury in water, so as to achieve the purposes of harmless treatment, water resource protection and the like. Background technique [0002] With the rapid development of modern technology, heavy metal pollution has undoubtedly caused serious harm to the ecological environment. Heavy metal pollution is a major environmental problem highlighted in the "Eleventh Five-Year Plan". The Party Central Committee and the State Council adhere to the concept of environmental protection for the people, and decide to deploy a series of actions to strengthen the prevent...
